本系统采用MSC-51系列单片机ATSC51和可编程并行I/O接口芯片8255A为中心器件来设计交通灯控制器，实现了能根据实际车流量通过8051芯片的P1口设置红、绿灯燃亮时间的功能；红绿灯循环点亮，倒计时剩5秒时黄灯闪烁警示（交通灯信号通过PA口输出，显示时间直接通过8255的PC口输出至双位数码管）；车辆闯红灯报警；绿灯时间可检测车流量并可通过双位数码管显示。本系统实用性强、操作简单、扩展功能强。 -The system uses MSC-51 series single-chip ATSC51 and programmable parallel I/O interface chip 8255A-centric device designed to control traffic lights, can be achieved in accordance with the actual traffic flow through the P1 port 8051 chip set red, green fuel Liang function of time traffic light cycle, the countdown five seconds left when the yellow light flashing warning (traffic lights through the PA output signal indicates the time directly through the PC port output 8255 to double-digits) vehicle alarm闯红灯 green time traffic flow can be detected through a double-digital display. The system practical, simple and strong extensions.

AT89S51读写I2C总线实验之1602液晶显示 单片机对I2C总线的读写在实际的测量中有很大的作用，比如用AT24CXX系列存储实验数据等，现用AT89S51读写24C02，为了使得读出的数据能直观的表达，所以用1602液晶显示。 -AT89S51 read and write I2C bus of the 1602 experimental single-chip LCD to read and write on the I2C bus in the actual measurement has a significant role, such as the use of experimental data storage AT24CXX series, are currently using AT89S51 literacy 24C02, in order to make read out the expression of visual data, so use 1602 liquid crystal display.
